The INSIDER Summary:

"The Walking Dead" actor Jon Bernthal has two full grown pit bulls and one pup.

He tells INSIDER he brings the two older dogs, Boss and Venice, to every movie and TV set he can.

Bernthal hopes to change public perception of the dogs. They often get a bad rap for being vicious fighters.

He says it's all about how you raise the dog. The breed of the dog "means nothing."

He suggests if you're going to raise a pit, it requires discipline. You have to be responsible and train them.

You may recognize Jon Bernthal from "The Walking Dead" and as Marvel anti-hero Punisher. Behind-the-scenes, he's known for bringing his pit bulls, Boss and Venice, to every film and TV set he works on.

Bernthal recently told INSIDER he likes to drive his truck to pretty much every shoot he can as long as it's not overseas. And when he does, he brings the two along for some quality time.

"They're great dogs. They've kind of grown up going from set to set," Bernthal tells INSIDER. Here he is with Venice (in his lap) and Boss during a recording session for "Call of Duty: Advanced Warfare's 'Exo Zombies'" in December 2014. Rachel Murray/Getty Images for Activision

But there's more to bringing them on set than just having two of his best buds with him.

"I know that there's a certain stigma that's attached to these dogs and what I really try to do with them is to change that, reverse that," Bernthal told INSIDER during press for his recent film "Shot Caller." "My dogs are enormously respectful. You know, they're very well trained. I really want to change people's idea of these dogs and of the people that have them."

"I would not put Bam Bam in a situation where he could go to set and run around like a crazy man," added Bernthal of his newest pit bull addition who he showed off in July. "When he's ready he will definitely be there [on set], but it's a good thing he's got great dogs to learn from."

But Bernthal says its silly to push the stereotype that any one dog will be born with certain characteristics. It's all about how you care for that individual pup and help it grow.

"Every dog is different, but the breed of the dog, in my opinion, means nothing. It's all about how you raise it. There's a responsibility with those types of dogs," says Bernthal. "I think you've got to train them. I'm not of the mindset that everyone should have a pit bull. I think that you've got to take it seriously. I think the fact that you have a dog that's enormously strong and athletic and has an enormous jaw, I think that that does not make that dog one bit more likely to attack or to hurt somebody. I think that's just vanity."

He likened people's quick assumptions of the dog breed to judging any individual simply by their looks.

"If you're a muscle bound guy who's walking down the street, you're no more inclined to behave a certain way," said Bernthal. "It just requires a certain kind of discipline and it requires a certain kind of outlook on life and I try to raise my dogs, again, as sort of respectful members of society. It's the way to do it. I think everybody should do it with all their dogs."

It's not just Bernthal who is trying to change people's perceptions of the dog. Sir Patrick Stewart rescued and fostered a pit named Ginger earlier this year before finding a permanent home for the dog. Stewart has shared videos of him and Ginger at his house encouraging others to consider adopting pets over shopping for them.
